Patented Sept. 26, 1944 UNITED STATES PATENT OFFICE LOCK OlinPdlSon, Chicago, 111. Application August 11, 1941, Serial No. 406,269 8 Claims. (01, 292-195) The invention relates generally to looks and more particularly to a lock for hinged members 7 such as doors or casement windows.

The general object of the invention is to provide a combined lock and seal for a hinged member such as a door, window or the like.

More specifically, it is an object to provide a locking device for a hinged member adapted to be'mounted in the free or opening edge of the member and coextensive with said edge so that the hinged member is locked along its entire opening edge, the device also serving as' a seal or weather strip for said edge when moved to its locking position.

A further object is to provide anovel lock which not only serves a a seal along the locked edge of the hinged member, but also causes the window to firmly bear against the stop extending alon said edge so that, in addition to being locked, the hinged member is-doubl-y sealed along said edge. g

Another object is toprovide a novel lock for a hinged member such as a. door or casement window, which cannot be forced open, which is easy to operate, and which is low in cost.

Still another object is to provide a novel seal ing construction for both the hinged edge and p the opening edge of a casement window or the like.

A still further object'is to provide a novel window construction having a metal" frame member adapted for use between two adjoining casement windows, the frame member cooperating with a lock on the opening edge of the sash of one window for locking and sealing that sash and cooperating with the hinged edge of the other sash for effectin a seal along said edge.

Other objects and advantages will .become apparent from the following description, taken in connection with the accompanying drawings, in which:

Figure 1 is a horizontal sectional view of a casement window embodying the features of the invention.

Fig. 2 is a vertical sectional view thereof taken on the line 2-2 of Fig. 1.

Fig. 3 is a fragmentary sectional view on the line 3-'3 of Fig. 1.

Fig. 4 is a fragmentary edge' viewzof the sash of the window shown in .Fig. 1. a

taken fled form of window.

Fig. 7 is a horizontal sectional view of another modified form of window.

Fig.8 is a horizontal section on a reduced scale of another modified form of window.

While the invention is adapted for any hinged element mounted within a surrounding frame element such as a door or the like, it is particularly'adapted for use with a casement window. Generally, a device embodying the features of the invention is adapted to be mounted at the opening edge of the hinged element for the purpose of locking said element to theframe element" and simultaneously providing a weathertights'eal. It is also of such construction: that it may be mounted either in the edge of the hinged element to cooperate with the adjoining portion of the frame, or may be mounted in the frame to cooperate with the adjoining edge of the" hinged element.

The preferred embodiment of the invention, when used in a casement window, comprises generally a member rotatably mounted in the opening edge of the sash and swingable from a position where it lies wholly within the perimeter of the sash, to a projecting position entering into a groove provided inthe frame. The member thus locks the sash to the frame and also, because it is coextensive with the length of the sash, provides a weather-tight seal between the sash and frame along the entire length of said edge. Moreover, when the rotatable member swings into the groove in the frame into abutmentwith one side of the groove, it forces the sash ,againstthe stop ordinarily provided in such window constructions. The sash'is thus doubly sealed.v To rotate the member, a simple form of actuator is provided which has a manually operable handle extending to the inside of the sash. This form of lock is preferably utilized with ais'ashwhich also has sealing means pr vided around the other three sides thereof so that the sash is sealed on its entire perimeter.

In Fig. 1 I have shown a casement Window construction comprising vertical frame members I 0 and stops lT'l on the inner side thereof against which a casement sash, indicated at 12, is adapted to abut whengclcsed. The casement sash 12 includes a pair of side stiles l3, one of which (the left-hand stile in the presentinstance) is secured to the adjacent frame member g of glass liseuredthereinin the us' ual manner.

-As heretofore mentioned, the "preferred embodiment of the invention includes a member rotatably mounted in the opening edge of the sash to engage the adjacent frame member I0. While the rotatable member may have other forms than herein shown, in the preferred form such member comprises a generally cylindrical bar extending the full height of the sash and rotatably supported therein by being mounted in a generally cylindrical recess 2| cut in the edge of the side stile l3. The recess 2| is of such size at its opening edge that the bar may be inserted therein from the edge of the sash. To retain the bar in place, a face plate 22 is secured as by screws 23 to the edge of the stile l3 and extends part way over the recess 2|, leaving a gap opening into the recess. The bar 20, while of generally cylindrical form, is cut away at one side thereof to provide a lip portion 24 adapted to extend through the gap provided by the plate 22. When the bar 20 is rotated, it is adapted to swing from a position where the lip 24 lies within the perimeter of the sash to a position where the lip extends therebeyond and into agroove 25 cut in the frame member Ill. The bar when it is thus rotated into the groove securely locks the sash to the frame.

Preferably the groove 25 is generally triangular in shape so that the lip portion 24 of the bar may abut against one side of the groove to form a seal, thereby effecting a weather-tight relationship between the sash and the frame for the entire length of that edge of the sash. Not only is the weather-tight relationship established along the entire edge, but also the locking relation is established along the entire edge so that the lock cannot be forced open.

This lock has a further advantage in that it forces the sash into tight abutment with the stop I I of the frame. To this end, the protruding lip 24 and the notch 25 are so shapedthat, as the bar 20 is rotated into locking position, it provides a camming action, forcing the sash firmly against the stop I Thus the sash is doubly sealed along the locked edge.

Means of simple construction are provided for readily rotating the bar 20 from its locked to its unlocked position. Said means comprises in its preferred form a member of arcuate form and embracing a portion of the bar, 20. Said member 30 is mounted for sliding movement along the bar in an inner recess 3| cut in the side stile l3 of the sash. To cause rotation of the bar 20 the member 30 is provided with a cam slot 32 intowhich extends a pin 33 mounted radially in the bar 20. Thus as the member 30 is moved along the bar 20, the cam slot 32 in cooperation with the pin 3| causes the bar 20 to rotate.

To slide the member 30 along the bar a hand lever 36 is provided which is pivotally connected as at 34 between a pair of lugs 35 extending from the rear face of the member 30. The hand lever 36 extends through a slot 31 cut in the side stile l3, and is pivotally supported by a pin 40. In order to compensate for the arcuate movement of the hand lever 36, the latter-is loosely mounted on the pin 40 so that the member 30 may have a rectilinear movement. The outer end of the hand lever 36 is provided with a handle 4| which is thus movable in the plane of the sash to actuate the look.

A seal is also provided at the hinged edge of the sash. Such seal preferably comprises a strip and is adapted to seat itself in a groove 43 cut in the hinged edge of the sash. The strip 42 is adapted to abut against one face of the groove 43, when the window is closed, to provide the seal, but in order to facilitate entrance of the strip into the groove one side of the latter is cut away on a slant as at 44.

The top and bottom edges of the sash are likewise sealed. For this purpose I provide a strip of metal 45 (See Fig. 2 which extends parallel to but in slightly spaced relation to the edge of the sash. To hold the strip 45 in such position it is provided with an angularly bent portion 46 forced into a groove in the edge of the sash.

.The strip 45 is adapted to interleaf with two in Fig. 6, I have shown a casement window adapted to swing inwardly. To this end the window comprises a pair of frame members; 50

having stops 5| onthe outerfacethereof. The

sash, indicated at 52, is hinged as at 53 to one of the frame members 50. The locking bar, in-

dicated at 54, is of the same general form and is provided with a protruding lip 55 similar to the lip 24. However, the lip is on the opposite side of the bar and abuts against one side of its cooperating groove in the frame member 50 in such a manner as to cause the sash to be forced outwardly against the stop 5|.

To rotate the bar 54 a, lug 56is formed thereon to extend into a recess 51 in the sash. The

lug 56 is provided with a slot 60 cooperating with I The nut 62 is mounted on a screw of the sash. By this construction, rotation of the handle 65 causes the nut 62 to be moved back and forth along the screw 63, thereby caus ing rotation of the locking bar 54. Such con- 55 and the groove in the frame member, as well as a seal between the sash and the stop- 5|. This sash may also be provided with sealing means at its other three edges similar to the means heretofore I described. V

In Fig. 7 I have shown anotherimodified form of window construction in whichther'e are two sashes, indicated at 10 and II. ini edge-to-edge relation and both hinged at their outer edges 62 (see Fig.1) set into a groove in the frame,

to the window frame. The sash 1| may be pro- .vided with the usual sliding bolts "I2 mounted H sash H is also provided with a, molding 13 on its outer face protruding beyond the edge thereof and overlying the adjacent sash 10. In thesash I0 I provide a combined lockand seal similar to that shown in Figs. 1 to 5, inclusive, but I arranged for an inwardly swinging sash. With such a combined lock and seal, the protruding 4 -,lip 24 of the locking bar is'adapted to extend into a groove 14 formed in the edgeof the sash Also the cam action of the: protruding lip 24 against the side of. the groove :14 causes the r sash L0 to becammedinto sealing relation with ,;,the molding 13. I

sashes',,---th ree' in the present instance, indicated at-8 0,8l and- 82. The window construction herein shown includes'metallic frame members, indi-cated generally at 83, extending'between adjoining'sashes and also at the outer edges of the I sashes 80 and 82'; The framememberscomprise strips provided at their outer edge with'rounded molding portions 34 serving as stops for the sashes. Each strip is bent along a longitudinal line to provide a groove 85 to receive the locking bar',.which preferably is of the form shown in Figs. l to 5, inclusive, and is mounted in the opening edge of the sash. The same bend in the strip also provides a protruding lip 86 adapted to interfit with a groove 81 cut in the hinged edge of the adjoining sash. Thus the frame member 83 is in sealing and locking relation on one side with the sash carrying the locking member and on the other side is in sealing relation with the hinged sash.

In the operation of the window shown in Figs. 1 to 5, inclusive, the window is swung inwardly to its closed position. The handle 4| is then depressed causing the member 30 to be raised. Such movement by the member 30, by virtue of its pin and cam slot connection with the bar 20, causes the latter to rotate and its protruding lip 24 to enter the groove 25 in the frame member H3. Locking is thereby effected. When the protruding lip 24 abuts against the edge of the groove 25, a seal is thus provided. Also, the cam action thereof forces the sash into tight abutting relation with the stop H so that the window is doubly sealed along that edge. Closing of the window also causes the strip 42 to enter the groove 44 in the hinged edge of the sash and to effect a sealing relation along that edge. To release the sash, the handle 4| is raised, causing the member 30 to move downwardly, thereby rotating the bar 20 so that the lip 24 of the bar lies within the perimeter of the sash. The sash is thus free to swing outwardly. The forms of construction shown in Figs. '7 and 8 operate similarly. In the form shown in Fig. 7, the locking bar effects a lock between the two sashes 70 and H, and also causes the sash 70 to abut firmly against the molding 13 on the sash H. In the form shown in Fig. 8, the metallic frame members 83 by their bent formation provide both the groove for the locking member and also the sealing strip entering into the hinged edge of the adjoining sash. Furthermore, the frame members 83 are provided with a molding portion acting as a stop for the sashes. The means for actuating the locking bar shown in Fig. 6 provides a simple rotatable handle 65 which, by a small amount of turning, causes the locking bar 54 to swing in and out of locking relation in the groove in the frame member.

From the foregoing, it will be apparent that I have provided a combined lock and seal for a hinged member such as a door, window or the like. The locking device is adapted to be mounted in the free and opening edge of the hinged member and is coextensive with said edge so that locking is effected along the entire hinge. The

' sash is doubly sealed along the edge by virtue of the fact that the lock itself forms a seal with the groove in the frame member and the locking bar by its camming action forces the sash into tight sealing relation with the stop on the frame.
